Working Theory

The Magnum Wideband Electronic Fuel Injection Enhancer was developed to adjust the exhaust gas oxygen sensor signal in the HHO converted engines. After installing a water4gas cell, more fuel needs to be processed to achieve extreme engine fuel consumption cranks up. After we inject hydrogen gas into the engine, the lambda probe reports a change in the consistency of the exhaust gas to the Engine computer, and accordingly the ECM tries to compensate the missing fuel by enriching the mixture. The lean fuel report will also indicate an trouble code, tripping the ECU warning light and then initiating the ECM safe mode. The Engine computer safe mode can dramatically ruin engine fuel efficacy improvements delivered by your H2O system. Wideband HHO O2 Sensor Adjuster is not intended to be a fuel saver by itself, but can warrant a palpable improvement if your Opel Meriva runs on Water4gas. In the case of a repetitive ECU warning light issue, an oxygen sensor simulator is required on OBD-II vehicles fitted with a multi-exhaust gas oxygen sensor system. Since the Air / Fuel Ratio in up-to-date EFI vehicles are supervised by the ECMs and most factory Electronic Control Units are set to maintain a 14.7:1 A/F ratio, known as a stoichiometric fuel mix, you are unable to trim manually or mechanically as you would on carbureted engines. Too much O2 will make the Power Control Module think that the mix is too lean. And due to the lean fuel signal, the PCM delivers more gas, and vice versa, if less O2 is sensed, the Engine management thinks the mixture is too rich and it will inject less gas to the engine. If you install a HHO cell, then the O2 content in the exhaust will significantly rise. The more powerful HHO kit you buy, the more oxygen will travel in the exhaust gas along with the hydrogen, and this will result in a fuel lean signal. As opposed to your original goals, the Electronic Engine Management will send more fuel to the chambers. We need to overwrite the Powertrain Control Module into thinking that the engine is still burning efficiently by fooling the Electronic Control Unit into sensing that there is less O2 in the exhaust than there actually is. Modification of the amount of voltage signal needed to accommodate the different amounts of hydrogen being led to your Opel Meriva engine is simply adjustable through the Magnum EFIE O2 Sensor Enhancer. The Magnum Wideband HHO O2 Sensor Adjuster will modify the exhaust air fuel sensor signal in a range of 0 up to 50%, delivering the Power Control Module a fluctuating fuel rich signal. As a result, the Engine management will enrich the air to fuel mix and you can effectively control the amount of standard fuel in order to obtain the big improvements in economy.

The Magnum adjustable Opel Meriva Wideband Electronic Fuel Injection Enhancer wires inline between the exhaust o2 sensor and the Power Control Module. The Electronic O2 Sensor Enhancer ramps up the A/F ratio by mimicking a fuel rich status. While you are injecting hydrogen gas into the engine, you need to lean the air/fuel mixture if you really want to save gas, otherwise the engine will run on an air to fuel blend of HHO that has too much standard fuel, ruining the engine performance and failing the engine mileage enhancement. As a rule of thumb, when you are driving on HHO, you have to feed the engine less regular fuel.

This Wideband EFIE O2 Sensor Enhancer works on your Opel Meriva if it is fitted with 5- or 6-wire lambda probe(s). This HHO chip will not work on titania or 1 up to 4-wire narrowband oxygen sensors.

Please check the sensor type prior to purchase or feel free to contact our Tech Team . The Magnum Wideband Electronic O2 Sensor Adjuster will help you get out of the closed loop - safe mode on your Opel Meriva by spoofing the exhaust air fuel sensor signal to the PCM, thus allowing the correct adjustments for various driving conditions to be made. Basically the lambda probe informs the Powertrain Control Module on its oxygen readings, delivering the Engine computer a fluctuating voltage between 0…1 Volts on narrowband sensors and 0…3 Volts or 0…5 Volts on wideband oxygen sensors. In order to adjust to a higher voltage that refers to a rich mix, the Electronic Fuel Injection Enhancer adds an adjustable voltage to the lambda probe voltage. This extra voltage compensates the variations caused by HHO. Adjustments to the trim screw can change the EFIE's voltage correction by 1 mV. This fine tuning will allow you to reach peak MPG and result incredible economy. The Wideband Electronic Oxygen Sensor Enhancer is a component of an HHO kit. Magnum Tuning bears responsibility for the functionality, the appropriateness of the cycle of the fluctuating lambda probe signal and the voltage adjustment but we don’t take responsibility for any fuel mileage gain realized or not realized on your Opel Meriva. Please be aware, we take responsibility for the appropriate voltage adjustment and the compatibility but do not warrant for fuel saving gains which depend on the overall setup of the particular hydrogen generator and the adjustments committed by either this EFIE or other enhancers, the volume of hydrogen produced by the HHO system, and the electronic pulse modulation of HHO cell. According to the sensitivity of the particular Engine computer, a MAP/MAF sensor adjuster might also be required in conjunction with the EFIE oxygen sensor enhancer.

An automotive oxygen sensor, also known as an O2 sensor, lambda probe, lambda sensor, or EGO (exhaust gas oxygen) sensor, is a small sensor inserted into the exhaust system of a petrol engine to measure the concentration of oxygen remaining in the exhaust gas to allow an electronic control unit (ECU) to control the efficiency of the combustion process in the engine. In most modern automobiles, these sensors are attached to the engine's exhaust manifold to determine whether the mixture of air and gasoline going into the engine is rich (too much fuel) or lean (too little fuel). This information is sent to the engine management ECU computer, which adjusts the mixture to give the engine the best possible fuel economy and lowest possible exhaust emissions.

5- or 6-Wire Wideband Oxygen Sensors

5-wire so called wideband oxygen sensors are more complex than standard zirconia sensors. A variation on the zirconia sensor, called the 'wideband' sensor, was introduced by Robert Bosch in 1994 but nowadays is used in only a few vehicles. It is based on a planar zirconia element, but also includes an electrochemical gas pump. An electronic circuit containing a feedback loop controls the gas pump current to keep the output of the electrochemical cell constant, so that the pump current directly indicates the oxygen content of the exhaust gas. This sensor eliminates the lean-rich cycling inherent in narrow-band sensors, allowing the control unit to adjust the fuel delivery and ignition timing of the engine much more rapidly. The wideband zirconia sensor is used in stratified fuel injection systems, and is also used in diesel engines to satisfy the serious EURO and ULEV emission limits. The ECM is watching the polarity and reference voltage. A value greater than 1.00 indicates a lean air/fuel ration; conversely a value less than 1.00 indicates a rich air/fuel ratio. At idle the lambda value will typically fluctuate between .90 and 1.00. The advantage to this is the fact that the pumping current can be monitored constantly for better AFR control whereas before we had the lag time between samples. Trends in the AFR can be monitored closer than ever giving us cleaner air and better mileage. So to put in a thumbnail sketch, the wide band O2 sensor is a conventional switching sensor combined with an oxygen pump. O2 is pumped into or out of the exhaust sample chamber in order to produce it's 450mv. The amount of oxygen required to achieve this is proportional to the oxygen content of the sample. The ECM supplies a pumping voltage to the ion conductive material that separates the exhaust gas sample chamber and the exhaust stream. As the pumping voltage, and thus the pumping current, increases or decreases, as well as changes polarity, oxygen ions will be moved from the exhaust stream through the ion conductive material into the exhaust gas sample chamber. Ions may also be moved from the exhaust gas sample chamber through the ion conductive material back into the exhaust stream. The ECM monitors the pumping voltage level and polarity required to maintain the 450 mV potential difference between the reference voltage circuit and the low reference circuit electrodes and uses this information to change the air/fuel ratio accordingly. This new commanded air/fuel ratio will burn in the engine cylinders, then pass the sensor, entering the exhaust gas sample chamber, and the adjustment process will start again. This process happens extremely quickly and thus makes the wide-range sensor much more accurate, fast, and able to detect greater deviations, rich or lean, from the stoichiometric air/fuel ratio.

can trace o2 sensor reading changes

its hard to notice any real change in idle or leaning, even with full settings but if you have an OBD diagnostic scanner, you can trace o2 sensor reading changes steadily. It would be nice to have control of the tuning on the unit or in dash as opposed to having to pop the hood. I have yet to see any gains in mileage with my (removed) HHO system and i drive my car over 150 km's per day. The design is nice and custoemr service was on the top.

Magnum Electronic Fuel Injection Enhancer was developed to modify the Oxygen Sensor signal when engine is converted to HHO. EFIE adjuster is a mist after installing a water4gas system. In this case more fuel needs to be processed to achieve ultimate MPG increase. After we deliver HHO gas into the engine, the oxygen sensor reports a change in the consistency of the exhaust gas to the Electronic Control Unit, and accordingly the ECU will compensate the missing fuel by enriching the mixture. That’s where EFIE adjuster comes to play.

Magnum adjustable Titania EFIE oxygen sensor adjuster wires inline between the oxygen sensor and the ECU. The EFIE Adjuster maxes out the Air Fuel Ratio by mimicking fuel rich status. While you are delivering hydrogen gas into the chambers, you need to lean out the air/fuel mixture if you are after real gas savings, otherwise the engine will run on an air / fuel blend of HHO that contains too much standard fuel, ruining the engine power and spoiling MPG enhancement.

Magnum Digital Map Sensor HHO chip has been developed to engines installed with water4gas generators. It modifies the MAP (Manifold Absolute Pressure) signal in fuel injected gas or diesel vehicles controlled by Electronic Control Unit. MAP sensor enhancer will allow you to gain full control of your MAP allowing you to lean out your air to fuel mixture to improve MPG.
